Cubit (Greek)
The Greek cubit is an ancient unit of length based on the forearm’s length—from the elbow to the tip of the middle finger. In ancient Greece, it typically measured about 18 to 20 inches (approximately 45 to 50 centimeters), though the exact length could vary by region and period.
The Greek cubit was widely used in architecture, construction, and land measurement. It played a crucial role in building temples, monuments, and other structures in classical Greece.

Micron
A micron is another name for a micrometer, a very small unit of length in the metric system. One micron equals one-millionth of a meter (1 micron = 1 µm = 0.000001 meters). Microns are used to measure extremely small things like bacteria, cells, dust particles, or the thickness of hair and fibers. For example, a human hair is about 70 microns thick. The symbol for micron is "µm". Though “micron” is an older term, it is still commonly used in fields like biology, electronics, and materials science to describe microscopic measurements.
